Raining and Dua Expecting Time

A Brief Description of the Question: 

A lot of people say that when the weather rains, the heaven doors are open and any dua what you pray for Allah will be excepted immediately.. Can you clarify is it a myth or true?

The Answer: 

Rain is mercy and an indication of the manifestation of the divine mercy. Therefore, it can be said that the prayers are answered more at those moments. However, it cannot be said that each prayer will definitely be answered at those moments.
